TOIIZL 10h 0m it may concern Be it known that 1, CHARLES CI JAMES, a citizen of the United States, residing in the city, county, and State of New Y rlr, have invented certain new and useful Improve" ments in Stopping Devices for Talking;- h'lachines, of which the following is a. specification.

lily invention relates to astopping device for talking machines and may be used in connzction with various types oi such machines upon. the marl et,.to wit, the Columbia, the Edison, the Victor, and other types. The object of my invention is to produce a. stopping: device which will stop the operation of the machine by cooperation with the end of the sound record.

A further object of my invention is to produce a device which is applicable to various lengths oi sound records.

Further, to produce a device which is adjustable to various sizes of machines.

A further object is to produce a leviee wheriin the action of the stopping means will not cause the rep'roducer to jump out of the groove.

A. further object of my invention is to provide an automatic means for feeding the stylus in coincidence with the sound groove without employing the stylus of the sound groove for such a feeding.

These and other objects. which will appear as the description proceeds, l attain by means of the devices whereof-the description is hereinafter contained and which are illustrated in the accompanying drawing; wherein Figure 1 is a plan view. of a talking machine having my improvement attached; Fig. 2 is a side elevation of the device shown in Fig, 1, the parts being broken away; Fig. 3 is a detail elevation of a brake-shoe forming part of my invention; Fig. 4 is an end view thereof looking from the left in Fig. 3; Figs. 5, G and 7 are detail ,views of an abutment connected to the reproducer carrier; and F 8 and 9 are respectively plan views and section of the connection between the rotary brake shaft and the axis.

1 have illustrated my invention as appliedto a Victor talking machine for convenience, but it is not necessarily limited in its use to such machine;

According to-my invention, a pair tot-nearable members is employed, one of which is a brake-carrying member and is given movement, in this case rotary movement, from the record carrier.

lettered A, has a capacity :for slight longitudinal movement whereby the brake B is brought into contact with a movable part of the machine. An abutment G 18 supported from the movable reproducer carrier, and in this case the movable part of the tone-arm, so that as said arm moves with the stylus in following the sound record the abutment likewise moves. The abutment G has a threaded connection with the shaft carrier A and the parts areso adjusted, proportioned, and operated that the longitudinal move ment given to the abutment by reason the rotation of the shaft, will coincide with.

th swinging movement given to the abutment by the movement of the reproducer carrier. Swivel and pivoted connections oi? the members permit these movements. it will be seen, therefore,-that so long as the reproducer carrier is moved by thesound record and the rotary record carrier, that no longitudinal movement of the shaft will take place. When, however, the stylus 'reaches the end of the sound groove the movement of the reproducer carrier will cease, whereupon the abutment will become fixed and continued. rota tion of: the brake s iatt will cause longitudinal movement of the said shaft "whereupon the brake B will gradually have braking contact with the movable part of the machine and its operation will be stopped.

The foregoing is an outline of the principal parts of the apparatus. A more de tailed description of the particular mechanism employed and of the advantages derived from the construction illustrated will now be given.

T he said improvements are illustrated in connection with a talking machine of usual type, wherein the record 1 is supported upon a turn-table 52 having an axis 3 constituting the record carrier, and the reproducer carrier comprises a tonearm 4:. having a 1novable portion 5 with the usual goose-heel 6 terminating in the stylus 7, which ope a in the usual manner by Contact with the c centric sound groove in the record 1, whe '1- by the reproducer carrier 5, 6, 7 has a swing ing' movement-from the periphery of the This member, which is shaft is moved by the disktoits center. The length of the grooves tary movement, likewisev as being capable,- of a slight longitudinal movement for the purpose of appliying a brake and releasing the same, and urther .as having a move-5 mentabout its pivotal axis for the purpose of permitting the movement in an arc of a circle of, the abutment C. The said shaft A on-its inner end is mounted between the arms of a bracket a (seen in detail in Figs.

8 and 9). This bracket has a cut-away portion a through which the shaft A passes and in said. cut-away portion is a gear a 'fixed on said shaft.

Upon the axis 3 is mounted a removable worm carrier a This has upon its underside oppositely dis-- posed notches a which are'adapted to receive the usual pins a with whichthe axis 3 is customarily equipped forthe purpose of driving the turn-table.-2 and the said worm carrier upon its upper side has corresponding projections a which are adapted to drive the turn-table; Upon this worm carrier, is a peripheral worm a. This serves the function of supporting the bracket a by revolving in an internal groove 0. therein and also of engaging and turning the gear a? and the rotary shaft A. -It will be perceived that in Fig. 8 the gear a is shown at the left hand side of the opening a in which position the brake B will be out of contact with the movable part of the machine with which it engages. The worm a has-a clockwise movement, as illustrated in Fig. 8, and the friction of the worm upon the gear causes the shaft to assume thisposition which it will retain as long as the parts are 1n operation. The space al how ever, is so much wider than the gear a that when the brake is brought into operation by the means hereinafter described, the shaft Ais permitted a longitudinal move- I ment sufficient to apply the brake.

Fixed upon the movable part5 of the reproducer carrier, to wit, the movable part of the tone-arm, is an arm D which is clamped thereon so as to be removable therefrom by means of the band (Z having flanges (if through which pass the clamping screw d. From this arm depends the abutment C. This arm D is fixed in position upon the movable part 5 ofthe tone-arm, where- :by as thesaid tone-arm swings on its pivot by reason of the travel of the stylus 7 in the sound record, the arm D will have a corresponding movement. Upon the outer end of the arm I) is the abutment C. Thisabutmentat its lower end is provided with oppositely. disposed slots 0, through which slots passes the rotary brake shaft A. Means are provided for causing an engage 'ment between the said shaft and the abutment, and as illustrated such means comprise a thread a upon the said shaft and a corresponding threaded engaging member E in the abutment. .The abutment is made hollow and within it slides a plug 6 which is perforatedat e for the passage of the rotary shaft A and which is spring-pressed downwardly by spiral springs e The plug 0 carries the knife-edged member E, which constitutes the thread engaging member,

and slidesin a bore of the plug eand is j springspressed downwardly by spiral sprin e. The bottom wall of the abutment 5 may be pressed inwardly as at-a to retain the said parts from dropping out of the said abutment.

.Fig. l'in dotted line position shows the posit on occupied by the arm I) and shaft- A at the end of the sound groove, and from this it ,will'be seen that the shaft A is capable, of movement about its pivotal support-- correspond in length to the minimum length of the sound record as the knife edge will slide easily over the unthreaded part of the said shaft, and it is desired that the thread ed part shall be as long as will ever be required for any sound record 'no matter how short. The brake B is composed of a braking'pad b which I prefer to make of some clinging material, and for this purpose-I have found sponge. rubber welladapted. This brake ismounted upon an arm 6, which in turn is perforated to receive the shaft A, upon which the said arm is adapted to slide. An adjusting sleeve F is mounted uponthe shaft A outside of the brake arm 6 and has a split spring shank f whereby p '120 could be employed, whether ency to cause the stylus y wilfilll) of. the brake this i o particular construction of as other types of brakes the longitudinal movement of .th the eriphery oi the turna other moving part. It will this brake has a' pull when in operationwhich is substantially peroendicular'to the he A 1 1S "1S oi longitudinal axis of the the said hralie'shaft i hralze is irregular, a

Ey'providing the ever, whereby the ca. the at substantially right er to the anisot the said brake shaft, an. by provi "ing iii-she substance, which is of material I have found that the in; 3;) ng effect upon the stylus is entirely overe roe and that the mechineis brought to a complete stop ua-l'ly.

it will be perceived that my improved hr'ake device may be applied upon a phonograph Without Iurther change therein than the addition of these hurts and such addition isefi'ected by simply clamping the arm D upon the tone-arm and by placing the Worm 'gear a and bracket asipon the axis 3. The Worm gear will thereupon he turned by the pins 10, with which such axis is customarily provided and will in. turn rotate the turn-table 2 by means of the piiis a which lie in corresponding grooves provided in such turn-tables.

I prefer-to provide the brake K with a pad as illustrated in 4%, Which is adapted toslide upon a fixed part of the apparatus and to regulate the inovei'nent of the brake and make the same uniform and to hold the brake in position against surface to which it may he applied.

'The operation of my'improved device is as i0lloWs:-lhe brake B Will he adjusted so that the-braking material. I) will just clear the outer edge of the turn-table when the rotary shaft A is in the position illustrated in Fig.- 1. T he movable part the tonearm will to enable the stylus? to enter the outer part or beginning of the sound record. This Will cause the abutment C to slide over the end of the brakei shaft A, and-tor this purpose the contact member it will ride over the thread and will slide down the plane portion of the said shaft to the proper noint.

if the machine previously had the brake applied as Will automatically release it. A. movement of tile axis 5 the record is turned will cause a corresponding movement of the abutment n toward the outer end of the shaft A. The shaft is rotated at a greatly reduced rate by means of the Worm gear so that its per eheral speed at the point of contact with the 'niember such as would cause the ahutinent G to travel at the same rate at which the regiroducer carrier causes i't-to thereby the said motions are neither will affect the other, hecause it will be apparent that if the said shaftinoves faster than the abutment it will apply the hral whereas if it noved slower it would. exer i o a retarding cii'ect upon i l hen the travel or" tile movable arm has progressed so far that the stylus has arrived at the end of the sound groove, the movement oi the abutequalized and -ment (7 will cease and the side wall of the sound groove will sonstitute a stop which w ll prevent further movement of the said stylus and consequently will hold the abut- -ment C in its fixed position. Thereupon a continued rotation of the shaft A fro1nthe axisv 3 will cause the soreW-thread acting in conjunction "with the screw-contact member E, to force the shaft A inwardly toward the axis. The play oi? the gel r a? will pen mit a suiiicient movement of this shaft inwardly to cause the braking material Z) to are of variable sizes ind thereby cause difi l e-rent rates 01 speed which require a different proportion of gears to, eii'ect the necessary reduction of the shaft A to correspond to the speed of the arm D.

The threaded part of the brake shaft may he made sufiiciently long to feed the reproducer throughout its engagement with the sound record grooves and to the point wherc the braking action begins. Under sukih circumstances the braking device has the fur thcr incidental and important function of threaded part of the repro ducer brake it, through its connection with. the re )roducer carrier,'p1"oviding a means Wherethe stylus may he fed forward without w. the side "Walls of "the grooves the reproducer carrier toward for this purpose, and whereby the wear upon,

the groove is prevented and an-absolute feed maintained irrespective'of any wear or inequality upon .the'wall of the groove.
